Notes..
- Dimensions are in millimeters unless otherwise indicated.
- The standard gap (opening) between the ends of butt welds is typically 1.5 mm to
3.0 mm, depending on the wall thickness of the material and the welding procedure specification
(WPS).
- The dimensions calculated on this page are based on a 3 mm gap.
- Dimensions are given in millimeters and are rounded up or down; for example, 168.3 mm is rounded
to 168.0, 88.9 to 89.0, and so on.
- Detailed dimensions can be found under “Flange and Fitting Dimensions.”
- as described: TYP stands for “Typical” and indicates that a dimension applies
to all identical, recurring locations in the drawing.
